Step 1: Prep Your Muffin Tin Preheat your oven to 350°F (175°C) and line a standard muffin tin with paper liners or spray with cooking spray. Don't skip this step—these Healthy High Protein Peanut Butter Chocolate Chip Cookie Muffin Cups can stick without proper preparation, and nobody wants to deal with that mess!

Step 2: Create the Wet Base In a large bowl, combine peanut butter, Greek yogurt, egg, honey, and vanilla extract. Mix everything until completely smooth and creamy—this takes about 2-3 minutes of vigorous stirring, but it's crucial for achieving that perfect cookie-like texture in muffin form.

Step 3: Add the Dry Ingredients Gradually stir in the protein powder and oat flour until just combined. Don't overmix—we want tender, fluffy muffin cups, not dense hockey pucks! The batter should look thick and rich, like the most amazing cookie dough you've ever seen.

Step 4: Fold in Chocolate Chips Carefully fold in the chocolate chips, making sure they're evenly distributed throughout the batter. I always save a few extra chips to sprinkle on top because, let's be real, more chocolate makes everything better in these Healthy High Protein Peanut Butter Chocolate Chip Cookie Muffin Cups.

Step 5: Fill and Bake Divide the batter evenly among the prepared muffin cups, filling each about ¾ full. Smooth the tops gently with the back of a spoon and sprinkle any remaining chocolate chips on top for beautiful presentation.

Step 6: Bake to Golden Perfection Bake for 14-16 minutes until the tops are golden brown and a toothpick inserted in the center comes out with just a few moist crumbs. Don't overbake—these are best when they maintain that slightly soft, cookie-like texture in the center.
